\(1449+\left\{\left[\left(6^3+184\right):2^3\right].9^2\right\}\)
\(\Rightarrow1449+\left\{\left[\left(216+184\right):8\right].81\right\}\)
\(=1449+\left\{\left[400:8\right].81\right\}\)
\(=1449+\left\{50.81\right\}\)
\(=1449+4050=5499\)
Vậy biểu thức trên = 5499
\(585-\left\{\left[\left(156+93\right):3\right]-3\right\}\)
\(=585-\left\{\left[249:3\right]-3\right\}\)
\(=585-\left\{83-3\right\}\)
\(585-80=505\)
Vậy biểu thức trên = 505
